Postioning the microphone

Boundary microphones make use of the pressure effects at a

room boundary and need to be mounted on a flat surface:

*) The cardioid pick-up pattern has an opening angle of approx.

130°. Try to position the microphone so that the sound source

(conference participant, speaker or instrument) is located in

this angle area (see polar diagram).
